Description

    BACKGROUND OF THE DISCLOSURE
  • 1. Field of the Disclosure
  • The present disclosure relates to the field packet-switched networks.
  • 2. Description of the Related Art
  • Packet-switched networks, such as Digital Subscriber Loop (DSL) networks, are used by service providers to provide a variety of services, such as Internet access, Voice over Internet Protocol (VoIP), Internet Protocol Television (IPTV), Video on Demand (VoD), etc. Often, service level agreements (SLAs) are made that specify quality of service (QoS) levels for the various services provided to the customers. The specified QoS levels or the service levels set by the service provider may be different for different services. For example, the QoS level for a voice service, such as VoIP, may be higher than the QoS level for a data service, such as the access to the Internet.
  • The ability to meet specific QoS level of a service depends upon a number of factors, such as the current load on the network and the capacity and condition of the various network elements, such as servers, routers, switches, the transport links that link the various network elements to the customer premise equipment (CPE). In many situations, the network may not be able to provide the requested services at the selected or desired QoS levels to all customers. If the network is overloaded, the quality of service may fall below an acceptable level for all the customers being serviced by the associated network. In some instances, such an approach may be acceptable for data traffic, such as Internet traffic, where in the long term the QoS levels are met and the effect in the short term can be tolerated, but not for the voice service.
  • Quality of service mechanisms have been implemented in routers and switches in an effort to provide differentiated services in packet-switched networks. These mechanisms generally operate by differentiating the data packets (“packets”) as they arrive at the router or switch, separating the packets into queues for each type of service, and then servicing each queue with a different priority to provide the desired service at a QoS level. These QoS mechanisms alone do not tend to control or police the access to the network and leave the network susceptible to overloading by a convergence of too many customers. Using a video service as an example, as the number of video service requests grows, even with a queuing scheme on video servers, the routers and switches can be overloaded, thus degrading the QoS level for all of the customers. Thus, there is a need for an efficient system and method for managing the traffic on a network so as to maintain the QoS at selected levels.

  • DETAILED DESCRIPTION OF THE DISCLOSURE
  • In view of the above, the present disclosure through one or more of its various aspects and/or embodiments is presented to provide one or more advantages, such as those noted below.
  • The present disclosure provides a system and method for managing traffic on a packet-switched network. In one aspect, the system controls customer access to the network so as to provide the requested services at selected QoS levels. In one aspect, the request for a service from a customer is routed to a server referred to herein as a Quality of Service (QoS) server that determines whether the network resources are available to provide the requested service at a selected QoS level, and provides the customer an access to the network if the network resources are available. In another aspect, the system notifies the customer if the access to the requested network service is denied.
  • In one aspect, the QoS server determines an overall load on the network to determine the network availability. In another aspect, the QoS server correlates the requested service to the available network resources. The requested service may be characterized by a QoS profile having one or more parameters, and each network element may be characterized by the value of one or more network metrics. The requested service may be correlated to the available network resources by comparing at least one parameter of the QoS profile of the requested service to a value of at least one metric of a network element. Network resources may be checked for availability by obtaining at least one value of a metric of a network element upon receiving a service request. Alternatively, network resources may be tracked by periodically or continuously updating values of the metrics stored in a database accessible to the QoS server. Updating may be done by any server, including the QoS server. In one aspect, the decision whether to allow the requested service may be performed based on a correlation of the requested service with network elements at one of a front-end, middle, and a back-end of the network. The decision maybe made on whether a metric meets a selected criterion.
  • The present disclosure further provides a system for enforcing a policy for the delivery of a broadband service. The system includes a packet-switched network for delivering a broadband service to a customer and a Quality of Service (QoS) server connected to the packet-switched network for monitoring a value of a pre-defined metric of the packet-switched network. The QoS server includes a database for storing real-time values of metrics of the packet-switched network, a processor, and a computer-readable medium that contains a set of instructions operative to cause a computer to execute a method. The set of instructions describes a method that includes: receiving a request for a service; correlating the requested service to available network resources; and making a decision to provide the access to the requested service based on a correlation result. The requested service may be correlated to available network resources by comparing at least one parameter of a QoS profile of the requested service to the value of at least one metric of a network element. A further set of instructions enables obtaining a value of at least one metric of a network element upon receiving a service request. A further set of instructions enables tracking available network resources by continuously updating a value of a metric stored in a database at the QoS server. The value of the metric may be updated in accordance with a change in the state of the network administered by the QoS server. In one aspect of the disclosure, the computer-readable medium of the QoS server further includes a set of instructions for performing a decision based on correlation of the requested service with an element at one of a front-end, middle, and a back-end of the private network. The QoS server typically notifies the customer of the decision.
  • FIG. 1 illustrates an exemplary system or network architecture 100 that may be used to provide the services to customers. The network 100 includes a service provider packet-switched network 104 that is adapted to provide the packet-switched services, such as the internet access, VoIP, IPTV, VoD, etc. to customers, such as customer 102, via a link 124. The network 104 is coupled to the Internet 106 via a link 126 and provides a data connection between the Internet 106 and the customer location 102. The customer location typically includes various customer premises equipment (CPE) designed to access a variety of services from the network 104. As shown in FIG. 1, an exemplary CPE may include an Internet Protocol Phone (IP Phone) 108 for transmitting and receiving voice content over the network 104 using, for instance, Voice over Internet Protocol (VoIP), a television set 110 for receiving and displaying a video content signal obtained from a the network, and a computer 112 for data transmission and reception, such as is commonly associated with an Internet connection, such as a Digital Subscriber Line (DSL) connection. The customer location 102 includes a Gateway 114 for providing a central customer interface with the network 104. A modem or a customer-side router are typical examples of Gateway devices.
  • The packet-switched network 104 may be a DSL network and may include one or more servers for providing one or more services to the customer gateway. One or more servers, such as a VoIP server 118, may provide a voice content to the IP Phone 108. One or more video servers, such as a video server 120, may provide a video content to the television 110. FIG. 1 shows an exemplary connection 126 to an outside network (i.e., Internet 106) that may enable the data content to be provided to the customer location. The network 104 further includes one or more switches 122 (122 a-122 e) that direct packets of data through the network 104 to their destination, for instance, from the video server 120 to the Gateway 114. The switches 112 may establish multiple paths for transmitting a signal between two points of the network. In one aspect of the disclosure, a switch 122 may also be a router, such as a core router of a network. The switches 122 a-122 e are shown connected to each other and the various network servers via links (also referred to as the transport links) 128 a-128 g, which may be physical links such as copper wires, fiber optic cables, etc.
  • In one instance, a switch 122 may be a Digital Subscriber Line Access Multiplexer (DSLAM). A DSLAM is a device used to provide DSL connections to multiple customer locations and to link multiple customer DSL connections into a single high-speed network, such as the network 104. The DSLAM generally aggregates signals from the multiple customers and separates these signals according to the signal type. For example, the DSLAM may separate voice signals and data signals, onto their appropriate networks, such as a voice network and a data network, respectively. For a DSL connection, the switch 122 a directly connected to Gateway 114 is often a DSLAM. Connection or link 124 may be a DSL connection, such as an existing phone line.
  • The network 104 further includes a Quality of Service (QoS) server 116 which regulates and manages the traffic traversing the network 104. The QoS server 116 may regulate traffic by providing a requested service to a customer when the network resources or elements have the capacity to provide the requested service at a desired or selected quality of service level. The various elements of the network (i.e., the video server 120, VoIP server 118, physical links 128 a-128 g, switches 122 a-122 e, etc.) may be characterized by one or more metrics that quantitatively specify the operational nature of the network element. As an example, a router may have a specified maximum bandwidth. The amount of available bandwidth through the router at any time depends on the specified maximum bandwidth of the router as well as the amount of bandwidth taken up by services currently using that router. As another example, a copper wire and a fiber optic cable may have different associated bandwidths and different packet loss ratios.
  • Each service (i.e., data, voice, video) may have an associated QoS profile or service characterized by one or more performance parameters. The performance parameters indicate requirements of a network element to deliver the service to industry standards of an acceptable quality. As an example, a video service, which generally has a lot of content, requires a network connection with a high bandwidth and that may support a steady bit rate. As another example, a voice service does not carry as much content as a video service, but requires that the content be transmitted without substantial delay at the switches, etc. Thus, a network may transmit a voice service if it has a low amount of available bandwidth as long as it transmits the signal without substantial delay. In yet another example, Internet data (e.g., web pages, etc.) may operate effectively even in a network with low bandwidth and with considerable delay.
  • Some exemplary network metrics include bandwidth, Mean Packet Transfer Delay (delay), Packet Transport Delay Variance (delay jitter), Packet Loss Ratio, and Packet Error Ratio. Bandwidth refers to the width of a communication channel and may be quantified as a number of bits passing a point per unit of time (i.e., Megabits per second (Mbps)). Mean Packet Transfer Delay generally describes an average delay for a packet traveling between two reference points, such as two endpoints of a network or two points within a network. Packet Transport Delay Variance generally quantifies variations in delay times. Generally, a bounded value of the Packet Transport Delay Variance is required for streaming applications (i.e., voice, video) in order to provide a smooth presentation of the stream. Excessive variations in the delay may result in buffer overflows and/or underflows, thereby resulting in either retransmission of a packet or negatively affecting the video or voice service. The Packet Loss Ratio generally describes the ratio of the number of lost packets to the total number of transmitted packets. The Packet Error Ratio generally describes the ratio of the number of transmitted packets experiencing an error to the total number of packets transmitted. Excessive packet error or packet loss may result in significant packet retransmission and negatively affect voice or video streams. Diagnostic tests are available to determine values of these metrics.
  • FIG. 2 illustrates an aspect of the network 104 of the present disclosure in which a request from a customer gateway 114 is routed to the QoS server 116. As shown in FIG. 2, the request to the network 104 may originate from a customer computer 112 for an access to the Internet 106. The request is routed to the QoS server 116 by the network elements 122 a and 122 d via the links 128 a and 130 respectively as shown by the line 202. The request may be considered as received or detected by the server 116 and the network 104 awaits an action from the QoS server 116 before taking any further action. The connection to the QoS server may be handled by a server in the network 104 or as a proxy through the Gateway. The request may take one or more forms. In one form, the request may describe the type of service being requested (e.g., Internet access, a video connection, a VoIP connection). In another form, the request may describe one or more parameters (e.g., continuous bandwidth, burst sizes, packet loss ratio, delay, delay jitter, etc.) of the QoS profile of the requested service.
  • Upon receiving the request, the QoS Server 106 determines whether the network 104 has the availability to provide the requested service at a selected QoS level. The QoS server may determine the current overall load on the network 104. If the load is below a threshold, the QoS server enables the network 104 to provide the requested service. The QoS server may correlate parameters of the QoS profile of the requested service with values of the network metrics. If the results of the correlation indicate that the network is able to support the service at a selected or pre-determined level of service quality, then the QoS server releases the request to the network so the appropriate network elements may provide the requested service. The QoS server also may deny the service if one or more of the network metrics is outside a norm or threshold. Thus, the QoS server in one aspect intercepts the customer request and releases the requests if the network 104 is capable of providing the requested services at the selected levels for those services.
  • The values of network metrics may be obtained at the time the request is received from a customer or may be maintained in a database accessible to the QoS server. The database may be periodically or continuously updated. One or more algorithms may be also be used by the QoS server to estimate the values of certain network metrics and provide the access if such estimates indicate that the network is capable to provide the service at a desired level of service. In one aspect, once a service request is received from the customer, the QoS server queries the network elements to return a real-time value of network metrics. Real-time values may be obtained by diagnostic testing (e.g., for testing copper wires, etc.) or by requesting a value from a database storing updated values at the appropriate network element, such as a database situated at a DSLAM or a database situated at a server. In another aspect of the disclosure, the QoS server continuously tracks the values of the metric of the network elements in a database at the QoS server and records any changes that occur in the value of the metric. When a service request is received, the QoS server may check parameters of the requested service against values of the metrics stored in the metric database of the QoS server. In one aspect, a change in the value of a network metric occurs whenever the QoS server performs an action, such as providing a service or ending a present service signal. Upon granting access, the QoS server updates the value of the metric at the QoS server to account for the effect of a provided service. When the service is terminated, the QoS server also updates the value of the metric to reflect the change.
  • FIG. 3 illustrates an exemplary connection that may be established upon providing access to the customer from the QoS server 116. Once the QoS server grants access, it reroutes the customer to the appropriate server and may also notify the customer that the access has been granted. For example, if the request is for an access to the Internet 106, then once the access is granted by the QoS server 116, the network will establish the internet connection between the customer gateway 114 via the routers 122 a, 122 b and 122 c over the links 128 b, 128 c and 126 as shown by the line 302. Similarly, if the request is made by the IPTV telephone, the network 104 will establish the voice connection between the VoIP server 118 and the customer gateway 114 via the routers 122 a, 122 d and 122 e over the links 128 a, 128 e and 128 f as shown by line 304. In the same manner, the network may establish an IPTV or VoD connection via the routers 122 a, 122 d and 122 e over the links 128 a, 128 e and 128 g.
  • Notification to the customer may take the form of a web page for a data connection or a dial tone for an IP Phone connection. If the QoS Server determines that the resources are not available to provide the requested service, the QoS Server may return an appropriate message to the customer to indicate that access is denied. For example, a request for VoIP service may return a busy signal, and a request for a data service may return an HTML page stating that the network resources are unavailable, etc.
  • FIG. 4 illustrates a block diagram of an exemplary QoS server 400 that may be utilized in the system of the present disclosure. The exemplary QoS server includes a metrics database 404 for storing values of metrics from various network elements (i.e., servers, links, switches), a processor 402 for performing calculations, and a database 406 of software and network diagnostic tests that may be implemented using the processor. The metrics database stores values of various metrics, such as bandwidth, router switching capacity, router queue depth, packet loss ratio, packet error ratio, etc., of one or more elements of the network 408. These values may be updated periodically to reflect a current state of the network. Values may be updated by using diagnostic tools to obtain the metric values or by requesting values from a database of an appropriate network element (e.g., router database, server database).
  • One or more software programs may provide diagnostic procedures for testing a network element, such as testing a bandwidth of a network link, for example. Another set of programs may request data stored at a network element, such as a server or a network switch. Another set of software programs may correlate values of network metrics with parameters of the QoS profile of the requested service to determine whether the value of the network metric meets a pre-determined threshold level.
  • In one instance, the QoS server may update the values stored in the metric database when it provides access to a service (or when a service link is terminated) by adding (or subtracting) the pre-determined values of the requested service. In yet another use, the metric database may store historical values of the metrics of the private network. The QoS server further includes a set of software programs which may be used by a network engineer to determine how to grow the network.
  • FIG. 5 illustrates a flowchart 500 describing an aspect of the disclosure in which the QoS Server responds to a service request from a customer. In Box 502, the QoS server receives a service request from a CPE device, such as a computer, IP Phone, IPTV device, etc. In Box 504, the QoS server obtains the value of the metrics of one or more network elements (i.e., switches, links, servers, etc.) of the private packet-switched network. In Box 506, the QoS server correlates the one or more parameters of the QoS profile of the requested service to at least one metric of the network. In Box 508, if the value of the pre-defined metric meets a threshold level of the requested service, then access to the requested service is granted.
  • In Box 510 in which the service is provided, the QoS server delivers an appropriate confirmation signal to the customer, such as a web page when data service is requested, or a dial tone to an IP Phone when a voice connection is requested, etc. Additionally, the QoS server redirects the service to the appropriate destination (i.e., video server, VoIP server, Internet connection, etc.) and assigns a priority bit to the service. If the QoS server does not grant access to the service (Box 512), the QoS server may deliver a message indicating that access is blocked. For example, if the requested service is a data connection, the QoS server may return a suitable web page with text indicating that access has been blocked. If the requested service is a VoIP connection, the QoS server may return a fast dial tone to indicate an inability to connect, etc.
  • In another aspect of the disclosure, the QoS server may correlate network metrics from a front-end, middle, or back-end of the network. For the exemplary purposes of the disclosure, the front-end may refer to the network elements providing a connection to the customer, such as the DSLAM and the DSL connection; the back-end may refer to the content servers, such as the video servers and voice servers; and the middle may refer to the internal switches and connecting links. As an example, the QoS server may check the front-end first before proceeding to a test of middle and back-end network elements. In this example, the QoS server may decide to deny access based on the DSL connection not having enough bandwidth. Alternatively, the QoS server may check back-end elements first and, for instance, deny access based on too many people trying to access a single video server.
  • By implementing the aspects of the disclosure, QoS guarantees and Service Level Agreements (SLAs) may be made for each individual service, and not necessarily for an entire port or connection. Each individual service may be handled individually. This enables control of how the services are loaded on the network resources and enables the network to efficiently provide these services. The methods described in the disclosure can prevent overloading of the network and enables different services to be transmitted at their selected or desired quality levels.
  • Additionally, the disclosure enables demand on the network to be measured by the number of service requests. This makes it easier to gauge the load on each of the network resources: link capacity, switch and router load, server load, etc. The network may thereby report how many services of each type were accepted, how many were blocked, and the limiting resource that caused each service to be blocked. This enables a network engineer to grow the network resources efficiently based on service demands.
